RF Communication Problems

If the RF link device and the printer are not communicating, try each of these suggestions to correct the problem.

♦Change or recharge the terminal’s battery.

♦Have your System Administrator ensure that the following communication parameters are set on both the terminal and the printer:

−8 data bits

−No parity

−9600 baud

−1 stop bit

−DTR flow control (on the printer) RTS/CTS flow control (on the terminal).

NOTE: The application on the terminal should be written with the parameters built in.

♦Re-link the printer and RF link device.

♦Move the modules closer than three meters apart.

♦Move the RF link device and printer around to find the best relative position between the two.

♦Swap in new devices (printer or RF link device) to narrow the problem down to a particular device.

♦Make sure no other RF devices are within the 20-foot zone because they may obscure the intended linking.
